I presently pull a Keystone Cougar Fifth-Wheel 312RLS 34, with my 2008 Chevy Duramax Diesel with 6 speed Allison Transmission. I went to a few large dealerships in Florida last week and noticed most all of the Class C MH were powered by Ford.

I told each salesman that I talked to, that when they have a Class C with a Duramax and a 6 speed Allison Tranny, give me a call. They agreed that it would be a good combo, but it's hard to teach an old dog new tricks(manufacturers) so I might be waiting for a while.
